John VanHart became one of Holland
Marsh’s pioneers when he immigrated
to Canada in 1947 & started VanHart
Farms. John became involved in the
research & development of farming in
Holland Marsh & in 1975, his son Ron
joined the business and they formed
Ontario’s largest producer of iceberg &
romaine lettuce. Since then, they have
continued to research organic farming
practices & now farm an acre of greenhouses
& 10 acres of field crops, which
produce vegetables from May to December
– a business Ron describes as
“challenging but rewarding.”
